LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Nov. 22, 1910.

Application filed January 31, 1910. Serial No. 541,131.

To all whom it may concern:

Be it known that I, BENTON MOORE, a citizen of the United States,residing at Cherryvale, in the county of Montgomery and State ofvKansas, have invented a new and useful Liquid-Fuel Burner, of which thefollowing is a specification.

The burner which is the subject of the present invention is designedmore particularly for use in connection with ordinary cooking andheating stoves, and it has for its object to provide an improved burnerin which a mixture of Oil, air and steam is sprayed into a pan locatedin the fire box of the stove.

Another object of the invention is to provide a burner of the kindstated which is simple in structure, and highly efficient in operation,and also one embodying certain novel structural details to behereinafter described and claimed.

The invention is illustrated in the accompanying drawing, in which-Figure 1 is a central vertical section, and Fig. 2 a plan view of oneform of burner, and Fig. 3 is a vertical section, and Fig. 4 is a planview of another form.

In Figs. 1 and 2 is shown a burner designed for use in connection with acooking stove. Vithin the fire box of such a stove, and preferablysupported on the grate thereof, is an open pan or tray 5 into which thecombustible mixture is discharged. The fire box of the stove is enteredby an air supply pipe 6 opening at one end through the door of thestove. The opposite end of the air pipe is enlarged and directeddownwardly into the pan, as indicated at 7, so as to discharge into thecenter of the pan. The discharge end of the air pipe is spaced a shortdistance above the bottom of the pan by legs 8. Located centrally withinthe down turned end 7 of the air pipe, is a cylindrical tube 9 which isclosed at its upper end, and open at its lower end, said lower end beingspaced 2. short distance from the discharge end of the air pipe.

Above the pan 5, and partly surrounding the down turned end 7 of the airpipe, is a steam generator 10 in the form of a pipe entering the firebox of the stove through the door thereof. On the outside of the stovethe steam generator is entered by a water supply pipe 11 of smallerdiameter than the diameter of the pipe forming said generator. The innerend of the generator terminates in an upward bend 12 from which areduced portion 13 passes into the down turned portion 7 of the airpipe, and enters the upper end of the tube 9.

Entering the outer end of the air pipe 6, and extending lengthwise andcentrally thereln, is an oil supply pipe 14, which is extended inwardlyas far as the down turned end 7 of the air pipe, and has connected toits inner end, by means of an elbow 15, a downwardly directed dischargenozzle 16 entering the tube 9 through the top thereof, and extendinglengthwise and centrally through said tube, the lower end of the nozzleterminating a short distance above the lower edge of said tube. The oilpipe is supported within the air pipe by means of a hook-shaped bolt 17carried by the air pipe. The tube 9 is spaced from the interior of thedown turned end 7 of the air pipe, and the discharge nozzle 16 of theoil pipe is spaced from the interior of the tube. The water and oilpipes are provided with suitable valves 18 for controlling the flowtherethrough.

In operation, water is turned into the generator 10, and a smallquantity of oil is run into the pan 5, and ignited. The flames from theburning oil play around the generator 10, and when the latter has beenheated to a suflicient degree, steam is generated therein, the steampassmg into the tube 9. The steam is discharged down the tube 9 in thedirection of the pan 5, and upon meeting the oil issuing from thedischarge end of the nozzle 16 is mixed with the same and sprays it intothe pan. It will be noted that the tube 9 and the nozzle 16 are spacedfrom the discharge end of the down turned portion 7 of the air pipe, sothat the air passing through the said pipe commingles with the mixtureof steam and air, and the resultant combustible product is dischargedinto the pan in which it burns with an intense heat, and without smoke,perfect combustion being effected by mixing the oil with the steam andair as described.

Figs. 3 and 4 illustrate a slightly modified form of burner, designedfor heating stoves. In this form of burner pan 5 is also supported inthe fire box of the stove, preferably on the grate thereof. An air pipe19 extends from the top of the stove in the direction of the pan, asuitable opening being made in the top of the stove in which the pipe ismounted. In the lower end of this air pipe is'located atube 20 similarto the tube 9, and entered by a steam pipe 21 connected to a steamgenerator 22 located above the pan 5 The oil pipe 23 is mountedlengthwise in the air pipe, and extends into the tube 20. The pan 5 iscircular in contour to conform to the contour of the fire box of thestove, and the generator 22 extends in a semi-circle above the pan.Above the pan 5 is located a lid 24 which is supported on said pan bylegs 25. The lid is spaced a short distance above the pan, and thegenerator 22 is located under the lid, there being an opening 26 in thelatter through which the steam pipe 21 passes to the tube 20. The lidalso has an opening 27 through which the air pipe 19 extends to the pan.The lid 24 acts as a deflector to throw the flames t0 the sides of thestove; otherwise, the operation of the burner is the same as the'onefirst described.

I What is claimed is:

l. A liquid fuel burner comprising a pan, an air pipe dischargingthereinto, an oil pipe in the air pipe, and discharging in the directionof the pan, atube surrounding the discharge end of the oil pipe, and asteam generator located above the pan, and connected to the tube. V

2. A liquid fuel burner comprising a pan, an air pipe discharging intothe pan, an oil pipe in the air pipe, and discharging in the directionof the pan, a tube surrounding the dlscharge end of the oil pipe, saidtube and discharge end of the oil pipe being spaced from the outer endof the air pipe, and a steam generator located above the pan, andconnected to the tube.

3. A liquid fuel burner comprising a pan, a lid above the same andspaced therefrom, an air pipe passing through the lid, and dis charginginto the pan, an oil pipe in the air pipe, and discharging in the.direction of the pan, a tube surrounding the discharge end of the oilpipe, a steam generator located above the pan beneath the lid, and aconnection between the steam generator and the aforesaid tube.

4. In a liquid fuel burner, an air supply pipe, an oil tube in the airpipe, and having its discharge end spaced from the discharge end of saidpipe, a tube surrounding the discharge end of the oil pipe, a steamgenerator, and a connection between the steam generator and the tube.

In testimony that I claim the foregoing as my own,I have hereto afiixedmy signature in the presence of two witnesses.
